I used PHP combined with Ajax. After adding data, I refreshed the front page and the data did not change.
I changed the PHP dynamic script, and I can only see the effect by re-opening IE and entering the address.
Are these the reasons for caching? How to deal with it?
How to solve the ajax cache problem:
It’s a cache problem.
Add header("Cache-Control: no-cache, must-revalidate");
Add a random or time string to your JS submission parameters
url+"?timeStamp="+new Date() .getTime();
The above has introduced the solution to the ajax cache problem, including the solution. I hope it will be helpful to friends who are interested in PHP tutorials.
